Re: [v8i] How to use MsdDimStackedFractionAlignment class

RJ:

I have tried to use"ElementEnumerator" but I encountered a Type Mismatch error.

We can't see your code, so we don't know...

• Where in your code the error occurred
• Whether it occurred at run-time or compile-time

Try using VBA's debug tools to step through your code (F8).

I have seen this in the help file and I do not know if it really works

Here's a scan procedure that looks for dimension elements...

Sub ScanForDimensions ()
  Dim oCriteria As New ElementScanCriteria
  oCriteria.ExcludeAllTypes
  oCriteria.IncludeType msdElementTypeDimension
  Dim oDimensions As ElementEnumerator
  Set oDimensions = ActiveModelReference.Scan (oCriteria)
  Do While oDimensions.MoveNext
    ProcessDimension oDimensions.Current.AsDimensionElement
  Loop
End Sub

Sub ProcessDimension (oDimension As DimensionElement)
  ... do something with dimension element
    Debug.Print "Dimension element ID " & DLongToString (oDimension.ID)
End Sub

The scanner is a common MicroStation  programming idiom.  It's used whenever you want to search a DGN model for some kinds of data.  An enumerator is a common programming idiom for iterating (enumerating) a collection of objects.  The ScanCriteria are a set of tests that let you filter the result of a scan.  In the above example, the criteria restrict the scan results to dimension elements.
